FM Receiver Silver
The FM Receiver Silver is a professional FM Rebroadcast Receiver which offers
great performance while remaining easily affordable for broadcasters. Designed
by WorldCast Systems’ experienced R&D team, the FM Receiver Silver is capable
of receiving a signal in difficult circumstances and outputting an MPX baseband
or audio signal which can be used for high quality retransmission by any make of
transmitter. This enables a broadcaster to provide complete coverage in shadow
areas, tunnels and other “hard to reach” areas.
To provide broadcast engineers with complete peace of mind, the FM Receiver Silver
will monitor RF levels and MPX deviation to establish the presence of a suitable
signal and display the current status via the LED front panel. The presence of Pilot
and RDS signals are also monitored and the PI code can be decoded to ensure
correct program tuning. Level meters offer a visualization of the current level of
audio activity.
Compatible with all makes of FM transmitters, the unit also provides a double MPX
output so it can also be used in conjunction with 1+1 or Dual Drive transmitter
systems. For those requiring additional monitoring capabilities, the IP/IO version
offers contact closures (GPIO) and a TCP/IP connection for remote configuration
and SNMP management.
